In that case, I said clearly that I did just that - "like John
suggested."  (I _normally_ run Emacs using `runemacs', to avoid
the command window.)

I had actually read that text.  (I saw it at the top level of 
http://sourceforge.net/projects/ezwinports/files/ - didn't
bother to download README.txt for ezwinports.)

One question is whether I need to use 7.10 for the backtraces
that you are requesting or I can use the "outdated version
7.6.1" that dispenses with needing to install python (which I
do not need).

In the latter case, perhaps the README should say where to get
7.6.1?  The text says only "The MinGW site offers it", with no
info about where that is (AFAICT).  Elsewhere in the README a
URL for MinGW (for libiconv) can be found, so I can indirectly
find the site: http://sourceforge.net/projects/mingw/files/MinGW/.
(There are 21 mentions of "MinGW" in that "README" text, but
there is only one URL that I can find, which is for libiconv.)

Eventually, searching each of the directories at
http://sourceforge.net/projects/mingw/files/MinGW/, I found gdb:
http://sourceforge.net/projects/mingw/files/MinGW/Extension/gdb/.

Should I use that, or must I really install python, just
to be able to give you an Emacs backtrace from gdb?

(This is already taking longer than I really want to devote
to this, FWIW.)

GDB 7.10 cannot be used without python?  Why is that?
(No, I don't really care.  It just seems odd, a priori.)
